The results of a paleoecological study of a peat deposit in Radomsky Mokh area (Smolensk Oblast, Krasninsky District) made it possible to reconstruct the history of the region's landscapes over the last 4 thousand years and identify its 4 contrasting periods. The reservoir was a lake at first, after which the pollen spectrum is dominated by pollen from native tree species. After a series of fires on the boundary of the Bronze and Early Iron Ages (3173–2969 14C calendar years ago) (2σ, 99.7%)) a forested mesotrophic swamp formed at the site of the lake, and pollen from pioneer trees with an admixture of alder started to dominate the pollen spectrum. At the third stage, the swamp became mesotrophic, and the landscapes around it become open, which is evidenced by an increase in the proportion of grasses and anthropogenic indicators in the pollen spectrum. The same period is marked with the appearance of pollen of cultivated grasses (2992–2912 simulated years ago), which coincides with the distribution of the monuments of the Dnieper-Dvinian culture in the study area. At the last stage, the swamp became oligotrophic, and a stable curve of cultivated grasses appeared (mid-1st Millennium AD), indicating the spread of agriculture in the study area. The absence of known archaeological sites in an 8-kilometer radius around Radomsky Mokh most likely indicates an insufficient archaeological study level of the area, whereas the economic development of the vicinity of the tract started at the boundary of the Bronze and Early Iron Ages.

A description is given of the processes of copulation, formation of the egg and spermatozoon, cleavage, embryogeny and hatching in B. phlebotomum. These processes were found to be essentially similar to those in other strongyle nematodes.The anatomy of the first three larval stages is described and the observations of Conradi & Barnette (1908) and Schwartz (1924) were largely confirmed.Penetration of the skin of calves by the infective larva was observed histologically. The larvae were found to have reached the dermis within 30 min. and to have penetrated the cutaneous blood vessels within 60 min. of application to the skin. The larvae were found in the lung where the third ecdysis was in progress 10 days after penetration of the skin. A description is given of the growth of the third-stage larva in the lung, the changes which take place during the third ecdysis, and the anatomy of the fourth-stage larva.The fourth-stage larvae exsheath in the lungs and travel to the intestine. After a period of growth in which sexual differentiation takes place, the fourth ecdysis occurs and the adult parasite emerges. The time required for the attainment of maturity was found to be somewhere between 30 and 56 days after penetration of the skin.This paper was written at the Ministry of Agriculture and Fisheries Veterinary Laboratories, Wey-bridge, and the writer would like to express his gratitude to the Director, Prof. T. Dalling, also to Dr W. R. Wooldridge, chairman of the Council of the Veterinary Educational Trust for their help and encouragement. The writer's thanks are also due to Dr H. A. Baylis, Prof. R. T. Leiper and Dr E. L. Taylor for their advice and help on technical points, and to Mr R. A. O. Shonekan, African laboratory assistant, for his able co-operation.

Background: Several risk factors have been identified for postpartum hemorrhage, one of which being the duration of the third stage of labour. This stage refers to the interval between the expulsion of the fetus to the expulsion of the placenta. Some bleeding occurs in this stage due to the separation of the placenta Objective: This study aimed to identify the factors associated with the length of the third stage of labour. Methods: In this cross-sectional study, 300 women hospitalized for vaginal birth were selected via convenience sampling. The study data were collected using a researcher-made questionnaire. Then, the data were analyzed using univariate and multivariate linear regression analyses. Results: The mean (SD) age of the participants was 26.41 (6.26) years. Investigation of the relationship between the study variables and the time of placental separation indicated that a minute increase in the length of membranes rupture caused a 0.003minute decrease in the time of placental separation. However, this time increased by 2.75, 6.68, and 2.86 minutes in the individuals without the history of abortion, those with the history of stillbirth, and those who had not received hyoscine, respectively. The results of multivariate analysis indicated that suffering from preeclampsia or hypertension, history of stillbirth, not receiving hyoscine, and not receiving misoprostol increased the length of the third stage by 4.40, 8.55, 2.38, and 6.04 minutes, respectively. Conclusion: Suffering from preeclampsia and having the history of stillbirth increased and using hyoscine and misoprostol decreased the length of the third stage of labour. However, no significant relationship was found between the length of the third stage of labour and mother’s age, gestational age, parity, mother’s body mass index, mother’s chronic disorders, history of manual placenta removal, length of the first and second stages, membranes rupture, induction, amount of oxytocin after delivery, and infant’s weight and gender.

The historiography of any historically significant phenomenon goes through several stages in its development. At the beginning − it is the reaction of contemporaries to the event they experienced, which is emotional in nature and is expressed in a journalistic form. The next stage can be called a retrospective understanding of the event by its actual participants or witnesses, and only at the third stage there does appear the objective scientific research bringing value-neutral assessments of the phenomenon under study and belonging to subsequent generations of researchers. The history of The Russian Diaspora and most notably of the Russian post-revolutionary emigration passed to the full through all the stages of the issue historiography. The third stage of its studying dates from the late 1980s and is characterized by a scientific, politically unbiased study of the phenomenon of the Russian emigration community, expanding the source base and scientific research methods. During the Soviet period in Russian historiography, owing to ideological reasons, researchers ‘ access to archival documents was limited, which is why scientific study of the history of the Russian Diaspora was not possible. Western researchers also could not fully develop that issue, since they were deprived of important sources kept in Russian archives. Political changes in the perestroika years and especially in the period after the collapse of the Soviet Union increased attention to the Russian Diaspora, which was facilitated by a change in scientific paradigms, methodological principles, the opening of archives and, as a result, the expansion of the source base necessary for studying that issue. The historiography of the Russian Diaspora, which has been formed for more than thirty years, needs to be understood. The article provides a brief analysis of the historiography, identifies the main directions of its development, the research problematics, and defines shortcomings and prospects.

This paper aims to introduce a search strategy and collecting comparable sentences of Arab-Malay corpus data. This method was introduced for the use of students, researchers and amateur translators to search and compare the structure of sentences in Arabic and Malay. The first stage is to collect data corpus with high impact titles from the press and must be able to enlarge the scope of study as stated by Maia (2003). The second stage is to search using the specified key words based on selected high-impact titles such as the Football World Cup year 2010 and 2014. Data search is by using Webcorp engine http://www.webcorp.org.uk/live/ corpus and also open database Google https://www.google.com. The third stage is to filter the data by using Aker et.al (2012) and Braschler's (1998) method based on similar story, related story and similar aspects. At the fourth stage every category is measured by Guidere's (2002) equivalence strength which is strong comparability (SC), medium (MC) and weak (WC). At the last stage comparable sentences between the two languages are compiled in parallel according to Mona Baker’s (1992) level of grouping which are sentence level, combination of words, grammatical, pragmatic and textual level. The result from data analysis based on Mona Baker and Vinay - Darbelnet’s (1995) comparable theory proved the existence of some sentences in large quantities are on the same level of comparability from the point of information delivery. This can be used as the basis of additional evidence concerning the validity of 'universal theory.' in the science of translation.

This paper describes the results obtained using an archaeogeophysical-based approach for discovering new Roman structures belonging to the ancient settlement of Forentum, currently identifiable by a well-preserved sanctuary from the third century BC. The investigated area has been affected by invasive anthropic activities that have partially damaged the Roman structures. Extensive geophysical measurements, including detailed ground-penetrating radar investigations supported by magnetometric data, have allowed for the identification of an impressive complex of structures composed of various buildings. Magnetometric and electromagnetic anomalies suggest the existence of an “urban” dimension close to the Gravetta Sanctuary, totally unearthed and unknown until now, organized into regular patterns in a similar way to the most famous site in the vicinity of Bantia, or the famous Apulian archaeological sites of Ordona and Arpi.

An algorithm to generate toroidal or helical cage structures has been developed. Any toroidal or helical structure can be generated following four stages. In the first stage a Fonseca type unit cell and its symmetrical counterpart is formed which represents one-fifth of a toroid. In the second stage one-fifth fragment of the torus is fully obtained by applying geometry optimization to the structure obtained in the first stage. In the third stage the torus fragment obtained in the second stage is reproduced five times and connected to each other to generate either toroidal or helical structure. In the last stage a final optimization process is reapplied to get the complete structure desired.

Many surgical procedures have been devised to manage laryngotracheal stenosis secondary to trauma. Laryngotracheal atresia is the most severe form and the most difficult to repair. The Meyer procedure is a three-stage operation that provides structural support that is covered with mucosa. A laryngotracheal trough is created and a carved trough-shaped cartilage graft is placed above and lateral to it in the first stage. The skin over the graft is replaced by buccal mucosa in the second stage. In the last stage, the cartilage graft with overlying mucosa is swung onto the trough as a composite flap replacing the anterior and lateral laryngeal and tracheal walls. Attempt at reconstruction was made in 8 patients. All but one lesion was secondary to endotracheal intubation. Two patients were unable to be taken to completion of the third stage. Of the remaining 6 patients, all have a functional voice and only 1 remains cannulated at night.

The article aims to show the experience of the Kazan Obstetrics and Gynaecology Clinic named after V.S. Gruzdev for replacing the obstetric operation manual removal of the placenta with other techniques to prevent serious postpartum complications. Research methods the historical study of primary literature sources. Manual removal of the placenta always associated with the risk of infection and developing puerperal sepsis. That is why obstetricians are constantly looking for a replacement for this operation. In 1895, even in the pre-Kazan period of work, professor Gruzdev successfully performed a method of inserting saline into the umbilical vessels to speed-up placental separation in the third stage of labor. While working in Kazan, on his proposal, doctor L.S. Sidorova (1936), and then Professor P.V. Manenkov (1942, 1948, 1955) and doctor M.V. Korotkova (1958) thoroughly studied and implemented the method of Budimilich in the work of the maternity ward of the clinic. This method involves replacing the saline solution with the crude alum solution. The second measure, preventing hemorrhage in the third stage of labor and avoiding manual removal of the placenta, was the successfully testing intravenous pituitrin (oxytocin) injection by Z.N. Yakubova, completed with the defense of her doctoral dissertation (1962). The high efficiency of these methods allowed us to recommend to them for widespread obstetric practice.

The analysis of the actual data on the age and stages of the channel systems formation in the Kama-Keltma lowland was based on the altitudinal differentiation of different stages of the relief and the results of radiocarbon dating of organics from the channel and floodplain facies. Late Pleistocene lake terrace is the highest level in the Upper Kama depression and Keltma hollow. The research into the geomorphological structure and age of deposited materials, with a particular focus on separate elements of the Kama-Keltma lowland erosive and accumulative relief, indicates the existence of six stages of the channel systems formation (reorganization). The first stage (end of the Kalinin stadial) is the Chepets hollow formation. The hollow was preserved after large-scale changes in the bottom relief of the Upper Kama depression. The second stage (Mologa-Sheksna interstadial) is the first Kama terrace formation. The third stage (Ostashkov stadial, 20-18 ka) is the period of the runoff hollow formation (including the ‘large terrace hollow’), which actively dissected the surface of aeolian landforms. The fourth stage (LGM, 18-10 ka) is the formation of the macromeanders of the South Keltma, Pilva, and Timsher, as well as the multi-arm channel of the Kama during alternating periods of relatively short-term warming and cooling. The fifth stage is the wide Kama floodplain formation in the Preboreal – Subboreal, represented by segmental generations. The sixth stage (modern) is characterized by the ‘straightening’ of the Kama channel – the formation of a relatively straight channel throughout the Kama-Keltma lowland.
